The Dealer told me that it did not exist, The B20 option but when I went out to the truck with him it was right there on one of the first screens that he pulled up. I forget what is was under but it's in there. Your service dork needs to open his eyes and stop texti his friends..... Lol
That is correct. The vehicle must be updated to the "bio-diesel" flash which is listed in the factory installation instructions.
